What is the enhancement in mind? How should it look and feel?
With the population so large, and the number of guilds appearing with similar names, it would be great if there was a subroutine (don't know if that is the correct term for lua) that could filter the /who results and only present == (exact) matches, rather than just provide a dump of the data presented from the /who command.

Please provide any additional information below.

As an example, I have alts in a guild 'War'. Doing a guild who search for war producers about 100+ results, with only 2 of them having 'war' as the complete guild name. All other guilds include dWARf are presented.

A command line option of exact would be brilliant.   I am looking to develop (with limited skill) a mod that uses your library and perform this within itself, but I imagined that this capability would appeal to many other mod developers and might make a good future release inclusion.

Thanks in advance for your consideration.
